From 7ec308d978019dd9aa0e7a756b5919e34431196d Mon Sep 17 00:00:00 2001 From: Kevin Rogovin Date: Wed, 15 Aug 2018 14:29:28 +0300 Subject: [PATCH] Add NV_fragment_shader_interlock support. The main purpose for having NV_fragment_shader_interlock extension is because that extension is also for GLES31 while the ARB extension is for GL only.
